lily invention r lates to irnproveznentsin doors for ovens such as areadaptable for use on the ovens of ranges or gas stoves or for portableovens,the object of the invention being to provide a door structurehaving a transparent panel and to secure said panel in place in suchmanner that it will be protected from breakage due to unequal expansionand contraction of parts;

With this object in View the invention consists in certain novelfeatures of constrnction and combinations of parts as hereinafter setforth and claims. v

In the accompanying drawings, Figure 1 is a front elevation of a doorembodying my improvements, Fig. 2 is a rear View, Fig. 3 is alongitudinal section and Fig. l is a face view of the plate 16 and theglass panel.

1 represents the main frame of the door and consists of a castingprovided at its lower corners with pintles 2 by means of which the doorcan be hinged to the front plate of an oven. The upper nieniberof theframe 1 is made intermediate of its length with an enlarged portion 3which forms a seat for a bracket 4: and this bracket carries a suitablelatch 5 and a handle 6 to operate said latch and to manipulate the door.The rear face of the frame 1. is provided near its corners and also atintermediate points with bosses 7 having threaded .socketsj8 for thereception of screws. Ledges or'seats' 9 are formed around the-inneredgesof the frame 1 for the accommodation of a sheet metal frame 10. Thisframe 10 may he nrovided at its outer edges with flanges 11 which abutagainst the intermediate bosses 7, and in this manner the sheet metalframe 10 is held against displacement. The frame 10,is made in its rearface near its inner edges with grooves l2,-'said grooves causing theappearance on the exposed outer face of the sheet metal frame 10, ofribs or heads 13. The inner edges of the sheet metal frame pointed. outin the metal frames 10 and i6 and so that the 1 In an oven door, thecombination with for the purpose of holding said sheet metal.

The sheet metal frame plate 16 is providednear its upper and lower inner edges and near one inner end edge withlugs 18 which projectdn direction toward the sheet metal frame 10 and attheir free ends, said lugs are provided with lies 19 which overhang theupper and lower edges and one end of the glass panello. This glass panelmay be slid into place from one end of the frame plate 16 so as tobecome disposed under the lips 19 of the lugs 18 and will he .heldihposition by means of a removable stop. This step may consi L of a nut:20 on a screw 21 which passes through the frame plate 16 near the inneredge at one end thereof.

engage the edge portions of the glass panel and enter the grooves 0rrecesses of the first mentioned sheet metal frame.

3. In an oven door, the combination with a main frame, of two sheetmetal frames, a glass panel confined between said sheet metal frames,one of said sheet metal frames provided with lugs near theupper andlower edges and one end of the inner. ortion of said frame, each of saidlugs provided at its ease-re said sheet metal frame and adapted to engage one end of the glass panel.

In testimony whereof, I have signed this specification in the presenceof two subscribing-witnesses. ERNST H, HUENEFELD.
